title: Fatal congenital Neospora caninum infection in a lamb.
abstract: Neospora caninum tissue cysts were found in the brain and spinal cord of a 1-wk-old lamb that was unable to stand after birth. The lamb was originally diagnosed as having toxoplasmosis, but ultrastructural and immunohistochemical techniques used in the present study permitted a definitive diagnosis of Neospora caninum tissue cysts in the brain and spinal cord of this lamb. This is the first report of N. caninum in sheep.
